STYROFOAM SIS by DOW
Structural Insulated Sheathing(SIS),Developed by Dow to help make building energy efficient homes easier for builders, STYROFOAM SIS™ is a 3-in-1 solution that provides R3-R5.5 insulating value, meets or exceeds structural codes, and is one-third the weight of OSB*. Because OSB and housewrap are not needed, STYROFOAM SIS™ reduces the number of trips around the house and saves on installation time and labor costs. The innovative STYROFOAM SIS™ Brand Structural Insulated Sheathing from Dow combines three functions in one product:
1. Structural lateral bracing and transverse loads
2. Significant insulation performance
3. Water-resistive barrier
In addition to providing the racking shear needed for exterior walls, STYROFOAM SIS™ blankets both the wall cavities and the studs to shield against thermal bridging which minimizes heating and cooling loss due to air infiltration. STYROFOAM SIS™ also helps move the dew point from inside the wall cavity (where mold and mildew can accumulate and go undetected) to outside of the wall cavity where it belongs, and, when taped at the seams and joints, STYROFOAM SIS™ meets code for water-resistive barrier.
Builders are incorporating STYROFOAM SIS™ into "green" package options for their customers as a point of differentiation. Made of up to 80 percent post-consumer recycled content by weight, STYROFOAM SIS™ is also ENERGY STAR-qualified and can save homeowners between $200- $500 per year*** in energy bills. The reduction in home energy usage helps reduce carbon emissions and may enable the use of a smaller HVAC unit, which could earn credits in the USGBC’s LEED program or NAHB’s National Green Building program.
The thermal performance advantages of STYROFOAM SIS™ can also help builders earn the $2,000 U.S. Energy Tax Credit for energy efficient homes built in 2009. STYROFOAM SIS™ provides a high R-value (R-3.0 at 0.5" or R-5.5 at 1.0") without having to extend window and door jambs, and is cost-competitive with wood sheathing and house wrap in many instances, so builders can promote the benefits of insulation with little to no added expense.
STYROFOAM SIS™ Brand Structural Insulated Sheathing has won an MVP Award for "Most Valuable Product 2009" from Building Products magazine, a Hanley Wood publication. STYROFOAM SIS™ was selected as a winner of this coveted award by a panel of judges comprised of builders, remodelers, architects and developers who evaluated product submissions based on their ability to reduce installation time, callbacks, or labor costs, and other factors that bring "value" to building professionals.
